Shortcoder incompatible with TinyMCE4

When editing a shortcode, the visual editor is shown but the text table is selected (strange!). When reclicking on the text table, it is possible to edit the shortcode and save it.
When trying to modify it by clicking on its button, an empty editing window is shown (code was gone).
If code is inserted through visual editor, all lesser than and greater than characters are wrongly encoded.
Visual editor should automatically be hidden for this plugin, that has serious issues.
